A smashed-up car from the movie set of Lethal Weapon Four and a large model of a World War Two bomber are among quirky memorabilia going under the hammer at a Gold Coast theme park.

More than 100 items are up for grabs when Warner Brothers Movieworld holds an auction.

Movieworld general manager Dianne Rigg says items like the Memphis Belle B-17 models are becoming harder acquire as movies shift towards computer-generated props and sets.

The auction will be open to the public today from 8am to 4pm AEST.
